. >> you did some reporting on president obama's south african trip, where president obama was very mindful of mr. mandela's health. remind the viewers of what president obama did when he went to south africa several months ago? >> well, again, i wasn't on that trip, but there was oncern, some talk even then. nelson mandela was in failing health at that time. that perhaps his visit to south africa could coincide with nelson mandela, his illness. he didn't go visit directly with nelson mandela at the time. their two lives, given their places in history, have intersected somewhat. we are waiting to hear what president obama says about nelson man tele. would not be surprised to have him appear on camera to discuss his legacy not only in south africa, but in the united states. there is a new movie out now about nelson mandela and his journey from an activist at the african national congress, to his imprisonment, his release and his rise to lead south africa, the incredible rise to lead south africa. no word exactly on what the president can say or when real hear something from president obama.
